Right. Escs might be sorted so while I wait on them I am ready to mount the armour.

I have a lot of mass behind it so I am still deciding whether to go for the normal hdpe or stiffer polypropylene.

When I mount with bolts and rivets I'm going to add some adhesive too. I have some polyurethanes, but could silicon help absorb shocks or would it be too thin to matter?
